Classification
Classification= Grouping things according to similar characteristics
Benefits of doing this?
Taxonomy= Science of classification
Taxonomic HierarchyDomain

Remember! Daring King
Phillip Came Over From Great Spain
Factors Used to Classify
Common ancestry= Fossil record may show relationships
Physical similarities= Very similar body forms in different species
Similar biochemistry= DNA and protein analysis
Embryonic development= Similarities in stages of developing embryos
Carolus Linnaeus1700s
Developed classification system
Used scientific names
genus + species
Latin
Petromyzon marinus
Three Domain System
Living things fall into three broad groups called domains.
Domain Archaea ( kingdom archaebacteria) Domain Bacteria (kingdom eubacteria) Domain Eukarya (eukaryotes)
This includes kingdoms Protista, Plantae, Fungi, and Animalia.
KINGDOM:ARCHAEBACTERIAMAY BE Directly descended from first organisms on Earth.
UNICELLULAR PROKARYOTES Cell Membrane; no nucleus Genetic Properties differ from ALL other life
Live in harsh environments such as Sulfurous Hot Springs, very salty lakes, and ice cores.
KINGDOM EUBACTERIA
They are UNICELLULAR PROKARYOTES. (Everyday bacteria)
Both autotrophic and heterotrophic.
Includes disease-causing bacteria such as tooth decay or food poisoning.
Both reproduce by binary fission
E. coli
Staphylococcus
KINGDOM PROTISTA
More than 50,000 species
Unicellular and a few simple multicellular EUKARYOTES.
Organism “junk drawer”
Many are aquatic.
Includes Euglena, Amoeba, and algae.
Amoeba
Euglena
KINGDOM FUNGI
Multicellular
Cell walls that contain a material called chitin.
Heterotrophic - obtain their nutrients by releasing digestive enzymes into a food source.
Fungi act either as decomposers (saprophytes) or as parasites in nature.
mushroom
KINGDOM PLANTAEEukaryotic, multicellular and autotrophic
Cell walls that contain cellulose.
Cells specialized for photosynthesis, the transport of materials, and support.
Kingdom Plantae includes mosses, ferns, cone-bearing plants, and flowering plants.
fern
Flowering plant (Poinsettia)
KINGDOM ANIMALIAMulticellular, eukaryotic, and heterotrophic.
Usually mobile organisms. Except sponges, barnacles, etc.
Fish, Birds, Reptiles, Amphibians, and mammals.
This Kingdom also includes sponges, jellyfish, worms, sea stars, and insects.
